Letters Patent No. 63,731, dated April. 9, 1867.

IMPEOVED MOP-HEAD.

fr TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM A. Lewis, of Springfield, in the county ofWindsor, and State of Vermont, t have invented a new and improvedMop-IIead;-and do hereby declare that the following is a full, clear,and i exact description thereof, which will enable others skilled in theart to make and use the same, reference being had tothe accompanyingdrawing, termin` part of this specification.

This invention relates to a new and improved mop-head of that class inwhich'the movable jaw is operated by a screw. The object of the presentinvention is to expedite the movement of said jaw,4or give it a morerapid motion than hitherto; and to this end my invention consists in theapplication of the screws, one ixed on the end of the mop-handle, andthe other, being a tubular one, 'provided with an internal thread, towork on tho xed screw, and also `provided with an external thread, onwhich a nut connected with the movable jaw works, ull being constructedand arranged to operate as hereinafter fully shown and described,

The accompanying drawing represents a side view of my invention. l

A is a portion of a wooden handle, having a metal tubular screwB, ittedpermanently on its end, and C i is a tubular rotary metal screw, havingan internal thread to work on the screw B, and also having two proijecting thumb-pieces ct a, for the convenience of turning it. The screwC is also provided with an external screw-thread, Zw, on which a nut, D,is fitted; and to this nut the inner part of the movable jaw E of themophead is secured. This movable jaw may be oi' cast or wrought iron, ofequivalent form, and provided with rounded corners, as shown clearly inthe drawing. F ie the xcd jaw, which may be cast or formed with the Ikedscrew B, and having a groove or recess in it's outer surfaceto receivethe outer side c of the movable jaw E. The two jaws E F are, or may be,constructed in the usual way, and therefore de not require .f1y specialdescription: t

It will be seen from the above description that, by turning the screw C,the movable jaw E will be moved rapidly, as the movement ofthe screw C,on the fixed screw B, is combined with the movement of the nut D, en thescrew C, in actuating said jaw; hence,`the` mop-cloth may be adjustedbetween the jaws and removed therefrom with thc greatest facility.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The operating thumb-nut C, provided with external andinternal screw-threads, in combination with the fixed screw B lon thehandle, and the sliding `jaw F, substantially osv and for the purposedescribed.

WILLIAM A. LEWIS.
